Description
Rainwater Harvesting is the collection and storage of rainwater that would otherwise flow down gutters into the drain. Rainwater is collected from the roof, then re-used within the home and garden. This can provide substantial savings on water bills, as well as making your home more sustainable.
By installing a rainwater harvesting system you will do more than help protect the environment:
• Reduce water bills by around 50%.
• Increase chances of your planning gaining permission. (Planners often favour environmentally friendly applications).
• Provide your garden with water during a hose pipe ban.
• Prevent flooding. Rainwater harvesting acts as part of a SUDS (Sustainable Urban Drainage System).
• Provide your home with soft, lime scale free, water for washing machines and toilets; helping to prevent breakdowns, and reducing the amount of detergent needed.
A rainwater harvesting system typically reduces mains water use by around 50%. The principle uses for rainwater are:
• Toilets (around 35% water use).
• Washing Machines (around 15% water use).
• Garden/Outside use (around 5%, yet this figure can grow greatly for keen gardeners).
Rainwater harvesting pipe (black with 4 green stripes) is mandatory for use between the tank and the home. 25mm and 32mm pipe is available in a variety of coil lengths.
Within the home, standard 22mm plumbing pipe work can be used. All interior pipe work including taps, toilets and outlets should be labelled every 0.5m to signify that it is rainwater pipe.
Use rainwater to water your garden to save on water bills and protect your garden during a hosepipe ban. As rainwater enters the tank, it is filtered heavily, taking out any moss or debris that may have come off the roof. Garden systems come complete with submersible pumps. This means you can utilise free, untreated water for hose pipes, sprinklers, irrigation systems or even pressure washers.
